Migration from Office Communications Server 2007

Microsoft Office Communications Server 2007 and Microsoft Office Communications Server 2007 R2 will reach end of support on January 9, 2018. To stay supported, you will need to upgrade. For more information, see Resources to help you upgrade your Office 2007 servers and clients.

The topics in this section guide you through the process of migrating from Microsoft® Office Communications Server 2007 to Microsoft Office Communications Server 2007 R2. If you intend for your Office Communications Server 2007 R2 deployment to coexist with a Communications Server 2007 deployment, this guide also includes some essential information for operating such a mixed environment.

This guide provides information specific to upgrading your existing deployment; it does not explain how to change your existing topology. This guide does not cover the implementation of new features. When a detailed procedure is documented elsewhere, this guide directs you to the appropriate document or document section.

Migration is one part of deploying your Office Communications Server 2007 R2 environment. You should be aware of how migration fits in the overall planning and deployment process. We also recommend that you read these migration topics in full before you start so that you know everything that you will need to do during migration.
